Modacrylic Flame-Retardant Tow
Modacrylic filament tow engineered with inherent flame-retardant properties for protective textile applications like firefighting gear. Falls under HTS 5501.30.00.90 as 'other' acrylic or modacrylic tow, characterized by at least 35% but less than 85% acrylonitrile content. Supplied in untwisted, continuous filament form for yarn production.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chopped into fire-retardant staple
Converted to staple form for nonwovens or spinning, it becomes synthetic staple fiber under 5503.
If processed into textile flock
Short-cut tow used as flock for coatings classifies under 5601, not continuous filament tow.
If not meeting textile fiber definition
If denier exceeds textile norms or lacks crimp, it may classify as plastic profile shapes.

Import Tips & Compliance
• Include flame-retardancy test certificates and polymer analysis to substantiate modacrylic classification
• Declare exact acrylonitrile percentage to differentiate from pure acrylic under statistical suffixes
• Avoid bundling with fabrics to prevent treatment as woven material under Chapter 55 headings
